PROCESS 0F MAUNG CONTAINERS.

Application led Ifetruary 20, 1923. Serial No. 620,281.

To all whom it mag/concern.'

Be it known that, l, WILMAM H. Rosa, a lcitizen of the United States, and residing at Jersey City, Hudson County, State of New Jersey, have invented new and useful lmprovements in lProcesses of Making Containers, of which the following is a specification.

My invention relates to containers and particularly to a process oi making containers from paper or similar material and simultaneously attaching heads thereto.

flhe object of theinvention is to provide a process by which the body of the container may be made from a strip of paper by rolling the same into tubular form and by which the heads for the container may be securely applied thereto during the operation of forming the body of the container.

My invention in its perierred forni is illustrated in the accompanying dravvin s forming part of this specication and in whichdig. lis a perspective view showin a sheet of paper being wound on a nriandre in the process-oiE formingthe body ot a container.'

Fig. 2 is a fragmentary longitudinal section' showings head secured to the body of the container.

Figs. 3, i and 5 illustrate diderent forms of fastening `means which may be employed for securing the heads to the body of the container.

ln carrying out my invention l preferably proceed in the following manner l take a strip of paper l0 and wind a portion of the same upon a mandrel ll this mandrel being rotated in any suitable manner and beingof sufficient diameter to produce 'a container of the desired size. ln this operation it is to be understood thats. suitable glue is applied to the paper so that the various layers are securely glued together as they are wraped about the mandrel.

Alter a desired num er oi layers ot paper have been rolled on the mandrel l then apply the heads to the partially completed body by slipping or forcing the same over the ends of the body. The heads which are designated by the numeral l2 are provided with aange i3 which dange is adapted to surround and closely t the partially completed body of the container. lin order to permit the heads to be applied to the partially formed body on the mandrel, it is of course necessary either to provide notches in the edge of the strip of paper material Or-in the flange i3 of the heads. In Figure 1 the strip 10 of paper material is shown notched at 14, which notches will of course permit application 'of a head 12 tol each end of the partially completed. bodv of the container. ln Figures 3 and 5 the dange 13 of the head is shown rovided 'with a slot l5 and where this expedient is employed it is oi course possible to apply the heads to the incomplete oody of the container without notching the edges of the paper strip. lt is of conrse'obvions that both the edges of the paper strip and the dange ot the heads may `be notched to a sucie'nt depth to permit the heads to be applied to theA unfinished body of the container.

Various means may be employed for insuring strong attachment of the heads to the with a series of openings 16 into which glue may penetrate thus producing an e'ective lock between the dange of the bead and the inner and outer layer oi paper material adjacent the flange. ln Figure 3 the dange 13 1s shown provided with a series ot inwardly projecting prongs 17 which are adapted to engage and embed themselves in the paper material when the head is applied to the partially formedI body. ln this form the dange 3.3 is also provided with glue receiving openings 16. ln Figure 5 the dange 13 is shown provided with a series of outwardly projecting prongs 18 and also with inwardlyprojecting prongs 17 like those oi Figure 3. ln this form it is of course evident that the inwardly projecting prongs will engage the partially 'formed body when the head is applied thereto and the outwardly projecting prongs 4will engage the material Wound around the outside of the dange 13. ln Figure i the dange i3 is shown provided. with a serrated edge which is bent outwardly to provide a series of sharp prongs i9 which are adapted to engage the ayers ont paper mit material wound.- upon the iange i3. lt is until the thickness of the tainer outside of the anges 13 is of the desired thickness, preferabl being continued od outside the flanges 13'is substantially equal'to the Width scribed and the opening 2() in such head provides for the application of the'usual cover or closure to the to of the container as indicated at 21 in Figure 2. Itis of course not necessary to provide an opening such as 2O in the head which is applied to the outer or free end ofthe partially formed container body, and such headmay therefore form a solid bottom for the complete container.

Having thus described the invention what is claimed as new and desired to be secured by Letters Patent isp:

1. The process ofmaking a container from a continuous strip of paper material and simultaneously attaching a head thereto, which consists in rollin a portion of the strip of paper material into the form of a tube, applying to such tube a previously formed head having a curved liange adapted to surround the end'of the tubev said flange and the marginal portion of said strip being ofthe radial flanges 12 formedon theheads constructed to permit said iange being slipped over the end of said tube, and then rolllng the rest of said strip of paper around said tube and said flan e of the head.

2. The process of ma 'ng a container from A a continuous strip of paper material and simultaneously attaching a head thereto, which consists in rollin a portion of the strip of paper material into the -form of a tube, ap lying to such tube a previously' formed ead having a cylindrical flange adapted to surround the end of the tube, and extend inwardly from the edge of said strip, one of saiddparts, that is, `said flange or the edge of sai strip, bein notched to permit said head being lslippe over the end said tube, and then rollin the rest of said strip of paper around sai tube and :flange of the head.

3, The process of making a container from a continuous strip of paper material and simultaneously attaching a head thereto, which consists in rollin a portion of the strip of paper material into the form of a tube, aplplying to such tube a previously formed' ead havin acurvediange adapted to surround the en of the tube, said flange and the marginal portion of said strip being ofy constructed to permitv said .flange being,

sli pcd over the end of said tube, and then ro ling the rest of said strip of paper around said' tube and said flange of t e head, said flange havin engagement etween the same and the paper material of the container. l

In testimony whereof I hereunto ax my signature.
